Great low latency Audio Interface
This is a great improvement over the previous USB 96 interface that I was using. Way more controls, very intuitive, and low latency. If I had to find a negative, I would say that the midi interface is not what I expected. Rather than the standard 5 pin connector that you would normally see, this has what appears to be a mini plug. Other than that, it's a great interface.

Best deal for small home studio
For the price this is an absolute deal, the price is covering a nice home studio interface, preamps are clean, latency is beyond good, but man, you are also getting the fender studio daw FOR FREE and a lot of useful stuff, so, maybe the motu is better, maybe the sslmkii is better, but lest be honest, you are not going to find a real difference between the other same tier interfaces but you are getting a great daw and plug ins that no other interface is giving you atm.

Quality interface, reasonable price
For the price, you can’t go wrong with this interface. It’s small enough to lug around, has top notch converters and looks nice. While it has a useful auto gain feature, there’s no DSP features.

Hard to use - standalone mode doesnt work out of the box and poor experience with Presonus suport.
I am not happy with the ease of use of the product and I am not happy with Presonus customer support either. Standalone mode didnt work out of box, I see the input LEDs wiggling, but the output LED doesnt wigge and I dont hear sound from this mixer. I thus decided to contact Presonus support The first call resulted in the support technician opening a support ticket. Subsequently, I have gone back and forth on the support ticket for a couple of weeks now and they have not sent me simple straightforward instructions to enable standalone mode. They provide a bunch of links and ask me to go look for the answer in there. What is the point of contacting support if the response is to read a bunch of documentation? Can they not type up a simple set of steps (without any links) that will help me fix the problem I have? Case in point - does anyone read documentation for how to operate an iPhone? I am unfortunately outside of the return window so the order is not returnable and Presonus said they wont refund me for this product. Alas, I have to live with this piece of hard-to-use mixer.

Decent interface for the money
There are things I like and things I'm not thrilled with. My last interface was a Presonus 24c. This interface is similar in sound quality but the layout is nicer. The top facing controls are easy to read and adjust while I play. I miss the mixer knob, but I found out how to use the interface in stand alone mode. I can't say anything about the software, I already use Studio One and I wasn't offered a new key. One last thought this interface is being replaced soon. Fender owns Presonus and decided to rebrand in 2026. The new Fender website does not mention this interface.

Işık rengi seçeneğiyle daha güzel olabilirdi
Sürücü, yazılım ve donanım oldukça yeterli ve sorunsuz; ancak Universal Control'ün ana paneli biraz karışık, iç içe menüler biraz yorucu. Mikser paneli ise yeterince düzenli. Işık rengini seçme olanağı olsaydı çok güzel olurdu, mavi ışık biraz can sıkıcı. PreSonus'a, Arial denen iğrenç yazı tipini arayüzde de donanımda da kullanmadığı için özellikle teşekkür ediyorum.

日本語版でユーチューブでも使い方が多数アップロードされているので初めてDAWを利用する私でも理解しやすいと思った
今回はアマゾンクレジットカードの6回分割が利用できたので購入しました StudioOnePro7を公式サイトで購入すると一括でしか買えず28000円するためブラックフライデーで金利0円4886円x6回支払いで購入出来て助かりました いざ溜めようとしてもなかなか貯蓄できなかったので助かりました ダウンロード版のDAWですが数千円でオーディオインターフェイスが付いてるので激安だと思います 一括で購入できるなら公式でも同じセット同じ値段で販売しています

Very nice unit
This is a nice unit once you get used to it. My only beef is that it doesn't have real time audio feedback as you record.
